Many of the keyboards we’ve looked at lately have been multi-device models, in that you can pair two or more computing devices—smartphones, tablets, PCs, Macs—to them simultaneously, and then switch back and forth with the touch of a button. Aside from Microsoft’s Universal Foldable Keyboard ($70), though, none have been small enough to consider carrying around with you – except Logitech’s Bluetooth Multi-Device Keyboard K480.

The K480 is compact and light compared to many multi-device keyboards, including those in Logitech’s line-up. It’s also inexpensive. Logitech lists it for $50, but we found it at several online outlets for around $30. At that price, the only real issues left are — does it, as its more expensive siblings and competitors do, perform well, and is it really portable?

There’s no shortage of mobile keyboards in the world. Some, such as EC Technology’s Bluetooth Ultra-Slim Keyboard and the Jorno Keyboard, fold in thirds. Others, including VisionTek’s Waterproof Bluetooth Mini Keyboard and today’s review unit, Microsoft’s Universal Foldable Keyboard, fold in half. Nearly all are water resistant to some degree, and most of them support all three of the standard tablet and smartphone operating systems: Android, iOS, and Windows.

Akin to its Surface 3 and Surface 3 Pro Type Cover keyboard sibling, Microsoft’s mobile keyboard is light, compact, and easy to use. And like most Microsoft keyboards (and other peripherals), it’s well-designed and well-built, if somewhat expensive. If you shop around, you can find it for around $70. You can pick up the VisionTek model for as little as $20, though, and the iClever BK03 Ultra Slim Mini Bluetooth Keyboard, yet another competitor, sells for about $36. At nearly two-thirds of a C-note, do you get what you pay for?
